Abstract

A server according to one embodiment displays on a map image a position corresponding to a user with consideration for user privacy. The server executes a program for outputting a map image including: a user specifying module configured to specify, based at least on a present position of one or more users, the one or more users for whom user elements are arranged on the map image; a determination module configured to determine a modification direction and a modification distance used to modify the present location corresponding to the one or more users thus specified; an arrangement module configured to arrange the user elements on the map image at a position corresponding to the present location modified according to the determined modification direction and the determined modification distance; and an output module configured to output to a terminal device the map image having the user elements arranged thereon.

Claims

1. A server for outputting to a terminal device communicably connected, a map image having one or more user elements arranged thereon, each corresponding to a respective user, the server comprising one or more processors capable of executing a predetermined program, the predetermined program comprising:

a determination module configured to determine, according to a request to output the map image, a modification direction and a modification distance used to modify a geographical position corresponding to a user having the user element thereof arranged on the map image;

an arrangement module configured to arrange the user elements on the map image at positions corresponding to the geographical positions modified according to the determined modification direction and the determined modification distance; and

an output module configured to output to the terminal device the map image having the user elements arranged thereon.

2. The server according to claim 1,

wherein the determination module determines the modification direction and the modification distance so that the modified geographical position falls into an area predetermined with reference to the geographical position before modification.

3. The server according to claim 2,

wherein the determination module determines the modification direction and the modification distance so that the modified geographical position falls into a first circular area having a first radius and centered at the geographical position before modification.

4. The server according to claim 3,

wherein the determination module determines the modification direction and the modification distance so that the modified geographical position falls into an annular area of the first circular area except a second circular area, the second circular area having a second radius smaller than the first radius and being centered at the geographical position before modification.

5. The server according to claim 1,

wherein the predetermined program includes a user specifying module configured to specify, based at least on one or more geographical positions each corresponding to the respective user, one or more users each having the user element thereof arranged on the map image, and

wherein the determination module determines the modification direction and the modification distance to modify the one or more geographical positions each corresponding to the respective specified user.

6. The server according to claim 5,

wherein the determination module determines the modification direction and the modification distance for each of the one or more users specified.

7. The server according to claim 1,

wherein the arrangement module arranges on the map image at positions corresponding to the geographical positions modified according to the determined modification direction and the determined modification distance, the user elements corresponding to users other than the user operating the terminal device to which the map image is outputted, and arranges on the map image at a position corresponding to the geographical position before modification, the user element corresponding to the user operating the terminal device.

8. A method for outputting a map image having one or more user elements arranged thereon, each corresponding to a respective user, the method comprising:

determining a modification direction and a modification distance used to modify a geographical position corresponding to a user having the user element thereof arranged on the map image, according to a request to output the map image;

arranging the user elements on the map image at a position corresponding to the geographical position modified according to the determined modification direction and the determined modification distance; and

outputting the map image having the user elements arranged thereon.
